Once I figured out the mechanics properly I really got into this! I don't think the force fields were rendering properly for me (they were totally invisible except when very nearby), but that might be related to the fact that I'm playing on linux using Wine. But I did eventually figure out how they worked.
It seems to me like some of the checkpoints aren't working, which made things a bit more frustrating than they probably needed to be. I eventually got to the monolith on top of the tower, and I very nearly got to the other monolith as well (came within one platform of it), but ultimately gave up (after at least an hour of play) as the lack of a working checkpoint on that section became too annoying With working checkpoints I probably would have completed it.
The setting is beautiful, and I like how the platforming feels fairly well integrated into the overall "world feel," if that makes sense. The audio is pleasant as well. The mechanics are fun and very novel (to me, at least). Overall, a very solid game!
